L4937NL

L4937NL is a Linear Voltage Regulator designed and manufactured by STMicroelectronics, one of the leading companies in power management solutions. This voltage regulator is perfect for applications where a stable, low noise and low power consumption power source is required. It is available in a TO-220FP, four pins and is an ideal choice for both switching and linear regulator application, especially for demanding mobile devices.

The L4937NL is suitable for use in a range of applications, including applications where a low quiescent current is required, such as battery powered applications. It is also highly suitable for applications with a high load requirements, security systems, portable devices and remote control systems. Additionally, it provides high reliability and protection from overvoltage and undervoltage due to its built-in overvoltage and undervoltage protection circuitry.

The L4937NL is perfect for applications which require a low-noise power supply, due to its highly efficient current regulation and low ripple. It has a high noise and stable output regulation over a wide input voltage range, as well as a fast-acting short circuit protection for protecting your system from any sudden voltage overloads.

The L4937NL’s working principle is based on linear voltage regulator technology. It utilizes a dynamic connection between an input voltage and output voltage that is regulated by a control voltage. The input voltage supply is connected to the control voltage, which generates a varying output based on the difference between the input voltage supply and the control voltage.

The L4937NL linear voltage regulator is designed using a MOSFET in the negative feedback loop. The MOSFET can be configured to either source or sink current, allowing the user to design and select the appropriate operating conditions depending on the application. The MOSFET is connected to the gate/source of the comparator, so as the voltage across the output of the regulator drops, the MOSFET will produce more current. This current then continues to activate the MOSFET, maintaining a constant output voltage.

Due to its high efficiency and wide application field, the L4937NL Linear Voltage Regulator is the perfect choice for many different types of applications. It is available in a wide range of configurable options, allowing the user to customize their design to meet the exact requirements of their system. As such, this voltage regulator is highly recommended for applications which require stability, low noise and low power consumption.
